"I am trusting you. Do not make me regret this decision." Felix said. Then he swiftly and skillfully used his long sword to cut through Nemo's shackles like they were butter. He did it with suck accuracy that not even a hair was out of place even after he sliced off the choker shackle. 

Felix then closed his eyes and focused feeling the mana waves. Felix could feel the presence two magi posted as guards outside the thick runic steel door to the cell. As he concentrated further he could feel the presence of at least thirty other magic waves intermingled on the higher levels. He formulated a plan and then opened his eyes. 

"Here is the deal. In addition to the runic shackles they use on prisoners, the entire prison is engraved with a scripture spell. The spell makes it impossible for spells to be cast unless you are wearing the runic bangle with the counter spell the guards wear. The runic bangles are nearly impossible to forge, as the only ones who have seen the incantation for the enchantment are the warden and the papal-magi. The only way to get one is to take it off a guard. And the only way to take it off the guard is to... kill him. There is another way to take it, severing the arm. There are two guards posted outside this cell. I am going to cut down the door but I need you to distract them directly after the door falls. If they see me, they will focus me, and it will make this more messy than it needs to be. After they have their focus on you, run. Dodge a few spells to make it look convincing but get hit by one. They are only authorized to use restraint spells, so getting hit by one isn't going to be a big deal. After you are restrained, one of them will have to pick you up. That is where I will come in. I will surprise the other one with a quick strike to the head with a manaegis punch, it should knock him out silently enough while the other's back is turned picking you up. I will then... extract the runic bangle, put it on myself, and use a spell to knockout the other guard. That will alert the other guards due to the magic register system. But we will be gone before they arrive. After reattaching the guard's severed limbs with a healing spell. I will transport us out of here before any of the other guards arrive." Felix explained. "Any questions?"
